Selective photocatalytic functionalization of diamondoids and iron-catalyzed hydrogen atom transfer of aldehydes

Wymore, Mikayla M.

Comparatively, the C–H bonds of aldehydes are somewhat weaker (about 90 kcal/mol). Multiple reports have been published utilizing aldehydes to generate acyl radicals; a common method to generate these radicals proceeds via a hydrogen-atom transfer (HAT) pathway. Chapter 3 showcases multiple examples of HAT pathways inv...

Association of interleukin-1α (IL-1α) expression with tumor aggressiveness in head and neck squamous cell carcinoma

Khan, Ishrat Nourin

Interleukin-1α is a pleiotropic cytokine that plays a pivotal role in triggering tumor-associated inflammation. Its expression is upregulated in multiple solid malignancies, including head and neck squamous cell carcinoma (HNSCC), and it has been associated with a more aggressive tumor phenotype with poor clinical outc...

Thalamocortical connectivity in children with distressful sub-clinical psychotic experiences

Barry, Amy

Transient subclinical perceptual events and odd thinking known as psychotic-like experiences (PLEs) can commonly manifest in children. In rare instances when PLEs are persistent or distressful, they may indicate high risk for later psychotic illness, such as schizophrenia. Numerous neurobiological and environmental mod...

Molecular insights into oyster neuroendocrine control of gonad maturation

Exposure to disengaged retail voters

Hutzler, Christian M

I examine how exposure to retail investors who do not participate in shareholder voting affects firms’ governance activities. This issue is important because most retail investors do not participate in voting due to the time, effort, and opportunity costs of voting. My analyses leverage decisions by Charles Schwab and...

MODULATION OF UV-INDUCED DNA DAMAGE FORMATION BY CYTOSINE METHYLATION AND TRANSCRIPTION FACTOR BINDING

Wilson, Hannah E.

Ultraviolet (UV) light is one of the most ubiquitous exogenous DNA damaging agents and is the primary etiological agent in skin cancers such as melanoma. UV light from the sun can be directly absorbed by DNA to induce helix-distorting lesions between neighboring pyrimidine bases, including cyclobutane pyrimidine dimers...

Discovery and characterization of a novel L,D-transpeptidase domain that makes essential 3-3 crosslinks in Clostridioides difficile

Bollinger, Kevin W.

In this thesis, we investigated the LDTs and 3-3 crosslinking in C. difficile. We discovered that VanW domains are a novel class of LDTs. Additionally, we found that 3-3 crosslinks and the LDTs are essential for viability in C. difficile, making it the first organism in which LDTs were shown to be essential. Loss of th...

Reading development in the early years of schooling in Australia: Teachers’ reported practices and perspectives implementing code-based reading instruction in the classroom (Citation and Abstract only)

Naidu, Rachelle

This national study investigated 254 Australian teachers’ reported practices and perspectives regarding the use of both decontextualised synthetic phonics instruction and contextualised analytic phonics instruction in Foundation – Year 3 classrooms. The study used a mixed-methods, quan-QUAL approach with data collected...

The development, evaluation, and field validation of biocide functionalized nanofiber material for the application of disposable personal protective equipment

Wei, Michelle

Second, we fabricated the same formulation from a 1.5 mL and a 0.3 mL precursor solution to make relatively thick and thin nanofiber layers, respectively, exposed these thick and thin nanofiber layers repeatedly to two different loadings of bioaerosols containing either E. coli (1.8 × 1010 and 5.8 × 107 CFU/mL) or bact...

Am I invisible? Asian American student activism at the University of Iowa, 1998-2008

Chang, Jin

Three research questions guided this study. 1) How did Asian American college students at UI understand panethnicity from 1998-2008? 2) How did Asian American students at UI engage in student activism from 1998-2008? 3) How did gender influence Asian American student activism at UI from 1998-2008? Through these questio...
